Before attempting to change the name of your VHM-314, keep the following risks in mind:
Because the VHM-314 is built as a budget-friendly minimal system, it lacks a native user interface, USB data port, or official smartphone application to alter its internal settings. Modifying the Bluetooth broadcast name requires a deeper understanding of the board's hardware architecture, chipset, and the specific methodology required to rewrite its non-volatile configuration memory.

Not in the dome, but in Archaic’s logic. A centuries-old sub-routine, "Project Genesis," auto-activated. Its directive: Repopulate the surface. For this, you will need more than workers. You will need ancestors. Vhm-314 Change Name
If the technical barrier or tool cost of editing the firmware is too high, consider these practical workarounds:
Go to Bluetooth settings, connect the VHM-314, and look for an option to "Rename" the paired device.
Changing this name—a process often referred to as —is highly desirable for identifying multiple devices in a home, branding a custom build, or simply making the device easier to recognize in your Bluetooth list. Before attempting to change the name of your
Select the correct COM port and set the baud rate (commonly 115200 or 9600 depending on the firmware version).
The VHM‑314 is a product of the global low‑cost electronics ecosystem. It is manufactured by several different Chinese companies (Zhanrui Electronics, Shenzhen Qianhai Ku Xian Sheng Industrial, and others). These companies are not incentivised to add user‑configurable naming; the module’s selling point is its price, not its features. As long as the VHM‑314 continues to be sold for under $5, it is highly unlikely that any manufacturer will invest the engineering effort to add a configuration interface.
Put the chip into its bootloader or program mode (which sometimes requires pulling a specific pin to ground during power-up, depending on the generation of the JL chip). Click the write/burn button in the software utility to upload the modified hex binary directly to the chip's memory. This link or copies made by others cannot be deleted
For most DIY builders, offers the cleanest path forward for commercialized projects, while Method 2 is ideal for quick, single-user home deployment. Attempt Method 3 only if you possess intermediate electronics diagnostic skills and have access to JieLi flashing software. If you want to proceed with a specific method, let me know: Which version or layout of the VHM-314 board you own?
Bluetooth names in cheap SoCs are tightly bound to memory constraints. Trying to change a 5-character name ( XY-BT ) to a 15-character name without restructuring the firmware code will cause firmware crashes.
